Abstract: The aims of this work are to check the experimental conditions for using of a $^{6}$Li-semiconductor-spectrometer at thermal reactor-systems and to measure the neutron-energy-spectra at the critical experiment KAHTER comparing with the theory. Using the spectrometer at thermal-neutron-experiments questions will be attended as resolution, statistic and selection of usable nuclear data.The nuclear data will be gauged by qualified measurements, the statistic will be estimated by simulated calculations and theresolution will be improved by using the Fredholm-equation in the calculations. The calculated spectra show a good agreement with the measured spectra. Only in the energy region of maximum distribution of fission-neutrons there are little difference. The measurements show the using of the spectrometer is recommended at systems with preponderant thermal neutron-spectra, althoughthe resolution and statistic are optimized for the spectrometer by measurements at experiments with fast neutron-spectra.
